METAL WINBOW-SASH.

. Patented May 18,1915.

Application filed January 17, 1913. Serial No. 742,568.

To al whom it may concern Be 'it known that I, BENJAMIN S. Mc- CLEL AN, a citizen of the United States, and

'. a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Metal Window-Sash; and I 'do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters. of reference'marked thereon, which form a part of this specification.

This invention relates to improvements in the construction of metallic window sash of K and vertical sash members at the corners of the sash. j

The invention consists in the matters hereinafter set forth and pointed out in the appended claim.

In the accompanying drawingsFigure 1 is a view in side elevation of one corner of a metallic window sash embodying. my invention; Fig. 2 is a sectional view of the same, taken on the horizontal line 22 of Fig. 1; Fig. 3 is a sectional view of the same, taken on the horizontal line 3-3 of Fig. 1; Fig. 4 is a vertical section, taken in a plane parallel with the side faces of the sash, on line 4-4 of Fig. 2; Fig. 5 is a vertical cross-section, taken on line 55 of Fig. 1;,

rig. 6 is a perspective view of the upper end of the sheet metal body part of the side member of the sash; Fig. 7 is a face. view of the right-hand end ofthe sheet metal body portion of the horizontal member of the sash; Fig. 8 is a view-of the top ofone end of the body part of the horizontal member of the sash, showing the body portion of the vertical side member of the sash in horizontalcross-sectlon, and m the process of 1nser-' tion between the side walls of said horizontal member.

As shown in the drawings, the lower horizontal rail of the sash embraces a body part or member A which consists of a piece of sheet metal bent to form two flat, parallel side walls a, a, and a horizontal integral connecting portion a which unites the said side walls with each other attheir upper or' inner edges. Said connecting portion a is bent and folded to form a flange a which constitutes one side of a I groove to receive the ,edge of the. glass C of the sash. The upright side member of the sash is provided with a body member B, consisting of a single piece of sheet metal bent to form two flat, parallel sidewalls b, b and an integral connecting part 6 by whichthe said side walls are joined at their innenedges'. Said connecting part b is bent and folded to form a flange 6 corresponding with the flange a of the horizontal -member A, and which forms one side of a groove in which is held the edge of the glass C.

'The members A and B are joined or united at the corners of the sash as follows:

In the case of one of the said members, in the construction shown, the member A, the metal of the connecting part a is cut away between the Walls a, a to a distance in wardly from the ends of the said side walls substantially equal to the width of the member B. The end margin a of the connecting portion a which is formed by so cutting away said connecting portion, is shaped to conform to the cross-sectional shape or contour of the inner edge' of the member B.

The said end margin a is, moreover, provided adjacent to the sidewall a with a notch 5 (Fig. 8) adapted to receive the inner flilnge b of the member B. In joining the meeting ends of the members A and B, the lower end of the latter is inserted into the space between the end portions of the side walls a, a of the member A, which end portions fit in overlapping relation against the outer faces of the adjacent ends of the sidewalls b, b of the said member B. Moreover, when the parts are so joined, the end margin 11 of the connecting portion a fits in abutting relation against the connecting portion 6 of the said member B, as clearly shown in Fig. 8, which illustratesthe parts in position with the body member B partially inserted between said side walls a, a. By preference, the side walls a, a of the member A are located at a distance apart, at their inner faces, equal to the distance apart of, theoute i faces of .the side walls 6, b" of the member B, so that the said member B may be inserted between the projecting ends of the walls a, a, when the'latter are left straight or fiatthroughout the entire length of the same. When the ends of the body members A and B are placed together in'in-' terfitting relation, as described, the overlap parts of the sidewalls thereof are permaneritly secured together by soldering,

brazing, or other means of attachment.

The external margins of the sash members are, formed by means of separate, U-.

shaped strips D and E of sheet metal,-of which the strip 1) is applied to the horizontal body member A and the strip E to the upright body member B. The side flangesd, 03 and e, e of the said U-shapedstrips I are parallel with each other, and at suchv distance ,apart as to embrace or receive between them the outer edges of the side walls a, a and b, b of said members, The said strips D and E are secured to the same by soldering, brazing, or other suitable attaching means. The meeting ends of said marginal strips D and E, at the corner of the sash, may meet or join each other in any desired manner, but as shown, the side walls of said strips are arranged in overlapping relation.

Within the body of the horizontal sash member is inserted a falling strip F, of wood or similar material, and in the bodyB of the upright member is inserted a like filling strip G. Said strips F and G are made of such thickness as to occupy the spaces between and fit closely against the side walls of the body members A and B, and are shaped at their inner margins (Fig. 2) to conform to the cross-sectional shape of the connecting parts (f, b of sand members.

' The said connecting portions 0, 6 ,of the body members A and B, are shaped to'form seats for metal beads or strips H, I, which are attached to the inner margins of said -members A and B, and serve to hold inplace the edges of the glass C; said beads formingwith the fixed flanges a and F, grooves to receive the said edges. As illustrated, the parts of the connecting members a 6 which form'the seats for the beads;

. H and I, are inclined or oblique with respect to the side faces of the body members A and B. The beads H and I are secured to the sash members by screws h and i, which are inserted through holes in the beads and in the oblique parts of the conthrough the j olting of the sash, it being understood that screws inserted in metal only often become so loosened. Another important purpose of the wood filling strips is to support and stififen the sheet metal sash members.

- As a means for giving additional strength and rigidity to the sheet metal sash, provision is made for rigidly joining or connecting the wooden filling strips F and G,

at the corner of the sash, as follows: The

end margin of the horizontal strip F is made flush with the end margin a oi the sheet metal body A, and, as before stated, is

shaped to conform to, and fit against, the connecting portion 12 of the member B. The end of the wooden strip G extends to, or terminates approximately'flush with, the adjacent e'nd margin of the body member B. It follows that the end portion of the strip G extends across the end margin of' the strip F, at right angles to said stri'p F, al-

though separated therefrom by the inter -vening connecting portion b of the member B. Said strips are rigidly attached to each other by one or more metal attaching members, preferably having the form of wood screws J, J, which are inserted transversely through the strip G and endwise into the strip F, and pass'through holes or apertures formed in the said connecting portion 6 of the body member B. The

screws or attaching members, thus applied,

serve to draw together the ends of the" wooden filling strips, so as to clamp the connecting portion 6 of the body member B, between them, thereby giving a much stronger and more rigid connection of the.

parts at the corner of the sash than would be afforded by the joining of the sheet metal members alone.

The sidewalls 1,, a, b, b of the sheet A metal body members A and B are made substantially narrower than the widths of the horizontal and upright members of'the sash, so that said walls terminate at their outer side margins at a distance inwardly from the inner surfaces of the U-shaped' marginal strips D and E, as clearly shown in the drawings, Figs. 3, 4 and 5. The wooden filling pieces F and G are, moreover, made of such width that their outer edges are within, or do not project beyond, the outer margins of said walls a, a and b, 6. Furthermore, the end margins of said side walls Fig. 4) are ,so' arranged that they are within, or do not extend outwardly past, the outer margins of said side walls at the corner of the sash. By reason;

of this construction, the said margina strips D and E, in applying the same to the body members, may be shifted or adjusted inwardly or outwardly relatively to the body members, so asto make the horizontal and vertical sash members of the desired widths; the said marginal strips being soldered or otherwise secured in place after being so adjusted.

By the feature of construction last described, the assembling of the parts constituting the sash, in a manner to make the sash accurately of the desired internal and external dimensions, may be accomplished with the expenditure of little time and trouble. The horizontal and upright body members need be made to approximate only in width and length the exact final dimensions of the sash. In assembling the parts, the body members may be placed together around a rectangular form or gage, by which the position of their inner edges will be accurately determined. The members will be then permanently joined at their corners and the wooden fillin pieces inserted and the screws J, J inserte therein. Thereafter the marginal members D and E may be applied to the outer edges of the body members, and adjusted thereon inwardly or out- Wardly until their outer faces are at exactly the required distances from the inner margins of the sash members. When in proper position, said marginal members will be permanently secured at their edges by soldering or otherwiseto the side walls of the body members.

A. metallic window sash embodying any one of the several features of my invention may be variously modified with respect to the other features thereof, as well as with respect to details of form and design, without departure from the spirit of my invention, and I do not, therefore, desire to be limited to the particular details of construction illustrated except as pointed out in the appended claim.

I claim as my invention A Window sash, comprising horizontal and vertical sheet metal body members, each having side walls joined at their inner edges by a connecting portion, the connectingportion of said vertical body member extending ing portion of the horizontal body member terminating short of the end of such member, said members being secured together 'to the end of such member and the connectwith the end portions of their side walls in overlapping relation, and with the end margin of the connecting portion of said horizontal body member abutting edgewise against and intermediate the ends of the connecting portion of the vertical body member, and means for holding the connecting portions of said members in abutting'relation, embracing filling pieces of wood or the like inserted between the side walls of said members with.the connecting portion of said vertical body memberinterposed therebetween, and fastening members inserted into said filling pieces and through the connecting portion of said vertical body member therebetween.

In testimony, that I claim the foregoing as my invention I afiix my signature in the presence of two witnesses, this 4th day of January, A. D. 1913.
